PERMANENT WAY FOR RAILVVAYS.

Application tiled March Z4, 1897. Renewed April l2, 1898. Serial No.677,377. (No model.)

To all whom t may concern,.-

Beit known that I, PETER HEVNER, a citizen of the United States,residing in Philathe stay-bars g to vthe upper flanges of the delphia,Pennsylvania, have invented certain Improvements in Permanent W'ays forRailways, of Which the followin gis aspecification.

The object of my invention is to provide a track or conduit structurefor undergound electrical or cable railways which While combining themaximum of strength, rigidity, and durability can be laid With rapidityand at a comparatively small cost. This object I attain in the mannerhereinafter set forth, reference being had to the accompanying drawings,in Which- Figure l is a transverse section of an undergroundelectric-railway structure in accordance With my invention. Fig. 2 is aplan View of the same with the concrete and surface paving materialremoved, and Figl is a similar View showing the slot-irons and theirbracing-rods removed.

A A represent the opposite rails of the track, which may be of anydesired character, those represented being the girder-rails now commonlyused in street -railway construction. The lower flanges of each of theserails are secured by means of clips a to a plate b, which is securelyattached to a girder or pier B, of artificial stone or concrete, thesegirders extending throughout the length of each raily and resting insuitable trenches dug in the street for their reception. If piers areused instead of girders, said piers will be properly spaced throughoutthe length of the track, this being regarded as an equivalentconstruction. The entire space between the rails and between theopposite rail-supporting girders or piers is dug vaway to form a trenchfor the reception of a mass of concrete D, in which are embedded theopposite Walls F of the conduit, Which converge toward the top and haveexternal base-flanges d and internal top flanges d.

Each wall F of the conduit is connected by stay-bolts f to the girder Bon that side of the conduit, and the top-plates of each girder are alsoconnected to the upper flanges of the corresponding Wall of the conduitby means of stay-bars g, the outer ends of these staybars beingpreferably secured to the capplates of the girders by the same boltswhich secure the rail-clips for the inner flanges of the rails.

The bolts which secure the inner ends of conduit-walls also secure thebase-flanges of slot-irons I, Which are mounted upon the top of theconduit-Walls and which preferably converge toward the top, so thattheir flanged upper edges form a slot of the desired Width for thepassage of the conductor-bar on the car.

The inner endsof the stay-bars g project beyond the top flanges of theconduit-Walls and serve for the support of depending bars J, which carrythe conductors t', the latter being in the present instance in the formof flat plates secured in position on the bars J by means of detachablebars m at the bottom of the latter.

Both ofthe plates z' may be positive con= ductors forconveying currentto the conductor-bar on the car, the return being through the rails ofthe track, or one of the plates t' may constitute the positive and theother the negative conductor of the circuit.

The slot-irons areA connected to the corresponding rails of the track bymeans of staybolts n, Which may extend directly from the slot-irons tothe rails, as shown at the lefthand side of Fig. l, or may be deflectedin their course, so as to be secured to the staybars g, in which casethe vertical stay-bolts p, which connect the transverse stay-bolts f andbars g, may perform the additional function of' connecting thestay-bolts n to said bars g.

The conduits carrying the feed-Wires can be conveniently laid in theconcrete mass on each side of the conduit-Walls F.

The conduit-Walls F may have flanged ends, so that the successivelengths of the conduit can be united by ordinary bolts and nuts.

It Will be apparent that when the formation of the trench in the streetis completed the laying of the track and conduit can be rapidlyproceeded With, the girders, with their cap-plates and anchors, beingreadily formed by molding the artificial-stone compostion in suitableboxes, and the operation then involving simply the proper assembling ofthe parts and the screwing up of the nuts upon the respectivebrace-bolts, after Which the concrete IOO filling D is put in place andthe surface-paving between the tracks applied thereto, so that thecompleted structure constitutes practically a solid homogeneous mass inwhich all the parts are held with positive rigidity in their properrelations to each other.

The inner projecting ends of the brace-bars g are slotted, as shown inFig. 3, for the reception of bolts, whereby the cond uctor-bars J aresecured thereto, so that said conductorbars .I can be moved from andtoward each other to accord with the requirements of any particularcase.

Having thus described my invention, I claim and desire to secure byLetters Patentl. The combination of the track-rails, girders beneath thesaine, a conduit disposed between the rails and below thc street-surfaceand composed in part of opposite side walls and in part of a mass ofconcrete interposed between the rail-girders and conduit-Walls, andextending beneath the latter to form the bottom of the conduit, andbraces whereby both the upper and lower portions of each of the sideWalls of the conduit are confined laterally to the railgirders,substantially as specified. 4

2. The combination of the track-rails, supporting-girders therefor, acentral depressed conduit, bars connecting the upper portions of theconduit-Walls to the girders and extending inward beyond the Walls ofthe conduit, and depending conductor-bars mounted upon saidinwardly-proj ecting portions of the bracebars, substantially asspecified.

3. The combination of the track-rails, girders supporting the same, acentrally disposed and depressed conduit,upper and lowerbracesconnecting the Walls of said conduit to the tiaclesupporting girders,and Vertical braces connecting said upper and lower transverse braces,substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.
